Swedish real estate giant Riksbyggen develops and maintains buildings across the country since 75 years. Some 350.000 people live in buildings managed by Riksbyggen. Maintenance of buildings is expensive, dangerous and surrounded by a lot of regulations and policies. Just imagine climbing snow-covered rooftops in the cold and dark Swedish winter. Riksbyggen have an innovative and business focused CIO who started study the development of drones for building maintenance 2008 to try save money, time, lives and the planet. Early this year they tried the DJI Phantom med 4K-camera and the concept worked. An inspection takes some 10 minutes instead of two hours and the result is digitally documented in 4K, ready to show the customer and to be saved for planning of future maintenance etc. Just to check the snow indicators on the roofs takes a couple of minutes for a whole block instead of having to climb up on each roof to take a look. With an IR camera mounted on the drone additional checks can be done. Today Riksbyggen has 9 trained operators and are currently running a pilot with a couple of customers. Imagine how many similar applications there are for drones to revolutionise!
